C++ noob

hallo,i am a university student and i am now staring to learn c++...i know quite a few things of java...
here is a part of my code

ifstream spammails[spam];
for(int i=0;i<spam;i++)
ifstream spammails[i](spamnames[i]);

(spam is an int,spamnames[] is a string array)

i receive the following error:
variable-sized object 'spammails' may not be initialized

what kind of initialialization do i have to make?give null values?

You should be initializing the variables spammails with the input file streams.

sorry,can you explain that a little bit?(i don't know much for the moment )

Your variable type is ifstream and so you should be initializing it with the values it can contain and that is input file stream.

well i am trying to initialize it with various input stream values
e.g

for(int i=0;i<spam;i++)
ifstream spammails[i]("something.txt");

(something.txt is a file in the same folder with the cpp file but i receive the same error) give me an example if you can....sorry and thanks in advance

Thats not the way of initializing it. Try referring to the document where you should find a good sample for ifstream.
